AutoRemote is asking for authentication. where to enable it?

[Zoran Vidanovic]

Hi, I am using AutoRemote on my phone/web(chrome extension) to request a file from another phone. The phone receives the request but complains about the file... "Unable to send to Last Sender: Error Sending Files: com.google.android.gms.auth.a: Not Authenticated" What do I need to authenticate and where? Thank you! Zoran
